Question

使用cmake编译一个简单的项目时，我得到了

    $ cmake CMakeLists.txt
    CMake Error: cmListFileCache: error can not open file /cygdrive/d/Balladen/helloWorld/CMakeFiles/CMakeSystem.cmake
    -- The C compiler identification is GNU 4.8.2
    CMake Error: cmListFileCache: error can not open file /cygdrive/d/Balladen/helloWorld/CMakeFiles/CMakeCCompiler.cmake
    CMake Error: Could not find cmake module file:/cygdrive/d/Balladen/helloWorld/CMakeFiles/CMakeCCompiler.cmake
    -- The CXX compiler identification is GNU 4.8.2
    CMake Error: cmListFileCache: error can not open file /cygdrive/d/Balladen/helloWorld/CMakeFiles/CMakeCXXCompiler.cmake
    CMake Error: Could not find cmake module file:/cygdrive/d/Balladen/helloWorld/CMakeFiles/CMakeCXXCompiler.cmake
    CMake Error: cmListFileCache: error can not open file /cygdrive/d/Balladen/helloWorld/CMakeFiles/CMakeSystem.cmake
    CMake Error: cmListFileCache: error can not open file /cygdrive/d/Balladen/helloWorld/CMakeFiles/CMakeRCCompiler.cmake
    CMake Error: Could not find cmake module file:/cygdrive/d/Balladen/helloWorld/CMakeFiles/CMakeRCCompiler.cmake

的CMakeLists.txt：

    cmake_minimum_required(VERSION 2.8.4)
    project('helloWorld')

    ## Target
    set(TEST_SRCS main.cpp)
    add_executable(helloWorld ${TEST_SRCS})

    ## Link libraries
    target_link_libraries(helloWorld ${CMAKE_THREAD_LIBS_INIT})

文件CMakeCCompiler和CMakeCXXCompiler不存在，文件CMakeSystem.cmake没有访问权限。因此无法阅读。

如果我从其他项目复制文件并为CMakeFiles中的所有文件添加阅读权限，那么它可以正常工作。我有几个项目的这个问题。在已安装的驱动器上运行它有帮助（例如在真正的加密驱动器上）。所以我猜测访问权限的问题。我在互联网上找到的所有提示都没有帮助。我正在使用Windows 7，Cygwin 32位，cmake版本2.8.9

有什么想法吗？

cmake无法打开文件
